Appendix A: Additional EFA solutions

Additional exploratory factor analyses (EFAs)

In Chapter III, I focused my interpretation on a subset of the EFA solutions suggested by the three factor retention protocols, excluding those solutions in which additional factors were redundant with the 3-factor (BODY-HEART-MIND) solution. These additional factors tend to explain very little of the shared variance; tend not to be the dominant factor (the factor with the strongest absolute factor loading) for many, if any, mental capacities; and tend to have very weak factor loadings. I include them here for completeness.

Study 1

The factor retention criteria employed in Weisman et al. (2017) suggested retaining 3 factors for all of the studies included in Study 1; see Chapter III. In contrast, parallel analysis suggested retaining 4 factors (instead of 3) for Studies 1b and 1d; minimizing BIC suggested retaining 4 factors (instead of 3) for Study 1c, and 5 factors (instead of 3) for Studies 1a, 1b, and 1d. See Figure A.1.

Study 2

All of the EFA solutions suggested by the three factor retention protocols are reported in full in Chapter III.

Study 3

The factor retention criteria employed in Weisman et al. (2017) suggested retaining 3 factors for all of the age groups included in Study 3; see Chapter III. In contrast, parallel analysis suggested retaining 2 factors (instead of 3) for younger children; and minimizing BIC suggested retaining 4 factors (instead of 3) for adults, and 1 factor (i.e., a “null” solution) for younger children (ages 4-6y). See Figure A.2.

Study 4

All of the EFA solutions suggested by the three factor retention protocols are reported in full in Chapter III, with the exception of the 1-factor (“null”) solution suggested by minimizing BIC for younger children (4-5y). See Figure A.3.
